Clues come together about deceased gunman Darion Aguilar

Almost a week after the fatal shootings at the Mall in Columbia, it appeared like a normal winter Friday with no obvious sign of the police investigation that remains intense and active into what provoked the 19-year-old gunman last Saturday morning.

Planned for Saturday morning, the mall will hold a moment of silence at 11:15 a.m., precisely the time last Saturday when shotgun blasts rocked a routine shopping day. Two Zumiez store employees were shot and killed before gunman Darion Aguilar killed himself.

Police held their last briefing Sunday, but through a series of Twitter messages this week, they revealed Aguilar kept a journal in which, they said, he spoke of a plan, talked of killing people but mentioned no specific targets, dates or location. He said he was ready to die, thought he needed a mental health professional and apologized to his family in advance.

Aguilar apparently was not a social media user. WBAL-TV 11 News has spoken with people who know Aguilar who describe him as very quiet, shy, with a small circle of friends. Rarely did he allow his picture to be taken.

He was well known at the mall, described by employees of stores adjacent to Zumiez as a mall rat, often hanging out with his skateboard on his shoulder.

A comment from a friend of Aguilar's on Facebook read, "He was quiet but the sweetest person ever. All you guys are only talking about him because he made the news. You *** went to school with him and didn't even *** notice him."

Still unknown is whether Benlolo and Johnson were specific targets. Is it just coincidence Aguilar and Benlolo lived just four blocks apart in College Park? What was Aguilar doing between 5:15 a.m. last Saturday and getting to mall by cab at 10:15 a.m.? And what was his purpose?

A spokesperson for the Zumiez company said Friday that Aguilar was not an employee of the store and had never applied for a job there.
